6201 NR Bearing Product Overview & Core Advantages
The 6201 NR is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Its key distinguishing feature is the snap ring groove on the outer ring, which facilitates secure and simplified axial location within a housing, eliminating the need for complex housing shoulders or end caps. Manufactured with precision P0 tolerance and standard CN radial clearance, this bearing offers reliable operation and high rotational accuracy. Its compact design, combined with high-grade chrome steel components, ensures long service life and robust performance in a wide range of industrial applications.

6201 NR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Simplified Assembly: The NR designation indicates a groove on the outer ring that accommodates a snap ring. This design provides a cost-effective and space-saving method for axial location of the bearing within the housing, preventing axial movement and ensuring precise positioning.
- High Radial Load Capacity: As a deep groove ball bearing, the 6201 NR is optimized to carry significant radial loads efficiently. The robust construction using chrome steel rings and balls ensures durability under demanding conditions.
- Precision and Reliability: Manufactured to P0 tolerance class (Normal) and standard CN radial internal clearance, this bearing guarantees consistent performance and smooth operation, making it suitable for a wide array of general-purpose applications.
- High-Speed Capability: With a limiting speed of 32,000 rpm, this bearing is capable of operating in high-speed environments. The stainless steel cage provides strength and stability at these elevated rotational speeds.
- Versatile Operating Range: The specified temperature range of -30°C to 120°C allows for reliable performance in various environmental conditions.
6201 NR Bearing Typical Application Areas
